The: distributor is illustrated as comprising an inverted troughfor distributing a solvent. lighter inf weight tliauthe'clarifying P a y teeth 34. The distributor 'compr1ses, ther'emedium, the sidemembers'co'rriprising a roof like structure, i filllditlle free edges30 being the loweriedges of,- the members,

The -side or roof members 27fand 28 therefore, *oasauae a receptacle to intercept? and retain the solvent: introduced through the inlet to cause the round 'stream of inlet 'solvent to spread. out over the cross sectional area represented by of the'roof rlembers, displacing thejcleansing medium of'higher specific gravity andilflowing over, the said edges i'n sheetlike form into "and through the clarifying material. Flangejor b'aflie members 32 and 33 extend 'dow nwa'rd lyfrom the lower edges of therOOf vnien'ubers "and .are preferably vertical f and ar'allel, and provided with serrations er fore, an inverted trough and the ."serrated flanges serve analogously t'ofweir-like walls of a normal trough so thatthe solvent isdi'stributed uniformly thereby over (the. entire length of the distributor "since the solvent, being 1 lighter than the clarifyin g solution in the sump, tends to rise r'a'ther" than-"to fall to; the bottompf the-sump.

The particles of solvent,therefore, have ample opportunity tointimately contact particles of the clarifying material and gasoline particles are eflectively distributed for passing through the precipitate element over sub stantially the whole area thereof. Substantially all of the clarifying material is,':thereforebontacted by theSol'v'ent all of the solv'entis thoroughly cleansed whereby both j economy-and;effectiveness in the use of the material are brought about.
